Novel Emergency Response Ventilator (NERVe)

A ventilator system using few parts and sourced from a supply chain completely separate from that of traditional ventilator manufacturers

Background

In mid-March 2020, a group of engineers and scientists at Lawrence Livermore National Laboratory (LLNL) initiated a skunkworks effort to address the projected shortfall in mechanical ventilators. Their goal; to prototype a ventilator system using as few parts as possible and sourced from a supply chain completely separate from that of traditional ventilator manufacturers. The team gained insights from medical professionals, ventilator manufacturers, and published guidance on ventilator functional requirements, particularly for COVID-19 patients.

Technology Overview

Ventilator Design

The team’s prototype is intended to be safe, simple and easy to build, while still achieving the minimally required functionality necessary to treat patients with COVID-19. The ventilator has two functional air flow circuits: an inhalation and an exhalation circuit ().
